Rubber Gasket on Regulator stem

[DrFubar]

I have a problem. I thought I might be having a leak where the regulator stem attaches to the CO2 bottle. At the very end of the stem is a rubber gasket. I pulled it out and was going to replace it. Holy mother of god I can't get the new or the old gasket back in the grove no matter what I try. Anyone have any ideas?

I did the same last weekend. I used keg lube around the gasket and carefully pushed it as far into the grove as I could then screwed the regulator back on. Seems to work just fine. Good luck!

Not sure what keg lube is but I can probably find something that's not going to be petroleum based.

Not sure that it needs to be waterbased: http://www.homebrewing.org/Petrol-Gel-keg-lubricant_p_628.html

You can also use Vaseline I think.
